Description

Technical Field

[0001] The utility model belongs to the field of water conveyance facilities in water conservancy projects, and particularly relates to a crack-resistant and seepage-proof water conveyance canal structure. Background Art

[0002] Channels are common water diversion structure forms in water conservancy projects. The water in the reservoir is introduced into channels at all levels in the fields, which are generally divided into five levels: main canals, branch canals, distributary canals, farm canals, and capillary canals. They play the role of water diversion. Generally, channels directly draw water from the reservoir and then form a water conveyance channel through gravity flow, using the height difference of the terrain to introduce water into farmland or storage pools. In the construction of conventional channels, the gravity flow form is mostly used. Due to cracks and sand holes in the channels, water seepage in the channels will occur, and cracks in the channels will also be caused by earthquakes and geological subsidence, resulting in waste of water resources, affecting the use of the water supply system, and unable to effectively utilize the performance of water resources. Content of the Utility Model

[0003] (1) Technical problems to be solved: Aiming at the defects that existing channels are prone to cracks and sand holes, resulting in water seepage in the channels, and cracks in the channels will also be caused by earthquakes and geological subsidence, resulting in waste of water resources, the utility model provides a water conveyance canal structure with high crack resistance and good anti-seepage effect, through multi-level waterproofing and crack resistance, to improve the anti-seepage and crack resistance coefficient of the canal, effectively reduce the damage degree of earthquakes and canal foundation subsidence to the canal, and reduce the situation of water resource waste.

[0004] (2) The technical scheme adopted by the utility model is as follows:

[0005] A crack-resistant and seepage-proof water conveyance canal structure includes a canal body. A channel installation groove is arranged on the canal body. A plurality of bearing columns are buried below the center of the channel installation groove. Cobblestones are filled between the bearing columns at the center bottom of the channel installation groove to form a cobblestone layer. A gravel cushion layer, a concrete waterproof board, and a gabion mesh stone layer are sequentially arranged above the bearing columns. The gravel cushion layer, the concrete waterproof board, and the gabion mesh stone layer jointly form a channel. An anti-filter geotextile and a rubber water stop are arranged between the gravel cushion layer and the bearing columns and between the inner walls of the channel installation groove.

[0006] Further technical scheme lies in that the rubber water stop is located above the anti-filter geotextile, and anchor piles are arranged at the shoulders of the canal body and below the anti-filter geotextile.

[0007] Further technical scheme lies in that a grid fence is arranged at the shoulders of the channel and on the top of the gabion mesh stone layer.

[0008] Further technical scheme lies in that a support beam is erected on the channel. Each end of the support beam is connected with a sewage interception net lifting rod. The sewage interception net lifting rod penetrates through the support beam and is slidably connected with it. A nut is threadedly connected to each sewage interception net lifting rod at a position above the support beam.

[0009] A further technical solution lies in that an overflow hole is arranged at a position on the inner side wall of the channel above the lifting rod of the sewage interception net.

[0010] A further technical solution lies in that the anchor pile has a structure with a larger upper part and a smaller lower part.

[0011] A further technical solution lies in that the depth of the bearing column is 1.5 - 2 times the height of the channel body.

[0012] (3) Due to the adoption of the above technical solutions, the beneficial effects of the present utility model are as follows:

[0013] 1. By burying multiple bearing columns below the center of the channel installation groove, cobblestones are filled between the bearing columns at the center bottom of the channel installation groove to form a cobblestone layer. A gravel cushion layer, a concrete waterproof board, and a gabion mesh stone layer are sequentially arranged above the bearing columns. The gravel cushion layer, the concrete waterproof board, and the gabion mesh stone layer together form the channel. The uniformly distributed multiple bearing columns are arranged in different forms, dispersing the bearing pressure of the channel and the water flow on the channel body. The cobblestone layer and the bearing columns act together to reduce the damage degree caused by earthquakes and the subsidence of the channel foundation to the channel, strengthen the stability of the channel, improve the crack resistance strength, and prevent cracks in the channel.

[0014] 2. A gravel cushion layer, a concrete waterproof board, and a gabion mesh stone layer are sequentially arranged above the bearing columns. An anti-filter geotextile and a rubber water stop are arranged between the gravel cushion layer and the bearing columns and between the inner wall of the channel installation groove. The design of multi-level waterproofing is adopted to ensure the requirements of channel anti-seepage. The overall purpose of high crack resistance strength and good anti-seepage effect is achieved. Through the water conveyance channel body structure with multi-level waterproofing and crack resistance, the anti-seepage and crack resistance coefficient of the channel can be improved.
